交汇契合与并行发展——探寻高等师范教育改革与基础教育改革的共同之路

基础教育与高等师范教育是人才成长的摇篮,而且是教育的两个不同等级的环节.基础教育对中小学生基本素质的形成与知识能力的培养起着不可替代的作用,基础教育质量的提高取决于中小学教师质量的提高;高等师范教育及高等师范院校是学生素质提升与能力提高的关键时期,高等师范教育的目标是为基础教育服务,双方的合作与交流是成功培养人才的需求和必由之路.     

网络生态伦理哲学基础与高校德育方法论

网络在给大学生提供信息便利的同时,也导致了他们自我约束力和道德法制意识的降低.而建立在因特网基础上的网络文化,也冲击着人类建立在现代化基础上的现代教育,使人们更加关注网络生态伦理问题.在网络生态环境下,高校应把"以学生为本"作为高校德育方法论的逻辑起点和价值取向,以"道德审美"作为高校德育方法论,以建构和谐的大学生网络生态伦理文化.

Assessing the effects of land use and land cover patterns on thermal conditions using landscape metrics in city of Indianapolis,United States

Direct applications of remote sensing thermal infrared (TIR) data in landscape ecological research are rare due to limitations in the sensors, calibration, and difficulty in interpretation. Currently there is a general lack of methodology for examining the relationship between land surface temperatures (LST) derived from TIR data and landscape patterns extracted from optical sensors. A separation of landscapes into values directly related to their scale and signature is a key step. In this study, a Landsat ETM+ image of Indianapolis, Unites States, acquired on June 22, 2000, was spectrally unmixed (using spectral mixture analysis, SMA) into fraction endmembers of green vegetation, soil, high albedo, and low albedo. Impervious surface was then computed from the high and low albedo images. A hybrid classification procedure was developed to classify the fraction images into seven land use and land cover (LULC) classes. Using the fractional images, the landscape composition and pattern were examined. Next, pixel-based LST measurements were correlated with the landscape fractional components to investigate LULC based relationships between LST and impervious surface and green vegetation fractions. An examination of the relationship between the LULC and LST maps with landscape metrics was finally conducted to deepen understanding of their interactions. Results indicate that SMA-derived fraction images were effective for quantifying the urban morphology and for providing reliable measurements of biophysical variables. LST was found to be positively correlated with impervious surface fraction but negatively correlated with green vegetation fraction. Each temperature zone was associated with a dominant LULC category. Further research should be directed to the theoretical and applied implications of describing such relationships between LULC patterns and urban thermal conditions.

Bridging the divide in urban sustainability: from human exemptionalism to the new ecological paradigm

This paper reviews the main bodies of contemporary urban sustainability theory. From this analysis, two underpinning paradigms of urban sustainability are identified: (1) The ‘Human Exemptionalism Paradigm’ (HEP), which emphasizes the ability of humans to overcome environmental problems—see Urban Sociology, Urban Ecology, Urban Geography, Urban Psychology and Political Economy; and (2) The ‘New Ecological Paradigm’ (NEP), which emphasizes the criticality of ecological limits to human progress—see Urban Metabolism, Energy/Emergy Analysis and Ecological Footprinting. Each of these approaches is critically reviewed, highlighting their main assumptions, theoretical and practical foci. It is argued in the paper that if the related issues of urban sustainability and development are to be progressed, there needs to be: (1) a greater maturation of the NEP approaches, which are ‘relative newcomers’ to the area of urban theory; and (2) greater integration and dialogue between the HEP and NEP approaches to urban sustainability than has hitherto been the case.

Applications and Implementation A SEPARABLE PROGRAMMING APPROACH TO EXPECTED COVERAGE: AN APPLICATION TO AMBULANCE LOCATION

The maximum expected covering location problem (MEXCLP) is reformulated using a separable programming approach. The resulting formulation—nonlinear maximum expected covering location problem (NMEXCLP)—guarantees optimality and also solves more quickly than previous heuristic approaches. NMEXCLP allows two important extensions. First, minor formulation changes allow the specification of the minimum number of times each node is to be covered in order to satisfy expected coverage criteria. Second, coverage matrices can be constructed that consider two different types of coverage simultaneously. Both extensions are useful for ambulance location problems and are demonstrated in that setting.

改革开放以来中国城市人口增长的最主要来源是人口的迁移增长 ,因此城市人口管理体制的重要一环是城市人口迁移的管理。本文根据城市人口迁移管理体制及其相关的问题进行分析 ,提出了要科学地依据自然资源与社会资源测定城市的人口承载力 ,对人口迁移增长的控制有科学的根据 ,对人口迁移增长有目标、有规划 ,并对城市人口迁移进行科学管理的创见     

Urban community as resource: Evaluation of the mentors in Toledo schools program

We report findings from an evaluation of the Mentors in Toledo Schools program (MITS), which pairs adult community volunteers with elementary school students in need of reading support. Begun in 2012, MITS now operates in five elementary schools in Toledo Public Schools. A quasi-experimental study of 379 students (n = 128 mentored, n = 251 comparison) tested the effectiveness of MITS, using changes (fall to spring) in students’ scores on STAR Reading. Multilevel models demonstrate students who participated in MITS made statistically significant, and educationally meaningful, reading gains compared to students who did not participate. Further, an investigation of the importance of dosage revealed that number of mentoring sessions is related to students’ outcomes; students who participated in reading mentoring at least once per week showed the most educationally meaningful improvements. We also report qualitative feedback from adult program participants, including teachers, mentors, and site coordinators, to help contextualize the STAR Reading results. These findings speak to the opportunity for community volunteers to act as low-cost and effective supports for urban elementary school students who are at-risk for reading failure.
